B-Guide System: Improving the Predictability of Complete-Arch Implant and Prosthetic Placement Using Fixed Prosthesis Guides.

Objective: Computer-aided implant placement (CAIP) offers improved accuracy and reduced invasiveness. However, traditional static CAIP (sCAIP) protocols for complete-arch restorations often involve multiple guides and clinical steps, increasing the risk of soft tissue trauma and procedural complexity. This article introduces the B-guide technique, which integrates implant placement and interim prosthesis delivery into a single device to simplify the procedure and minimize tissue damage.

A novel coded healing abutment for a simplified digital workflow: A retrospective clinical study on 103 patients with a one year follow-up.

Objectives: To present the clinical results obtained using a novel coded healing abutment (CHA).

Methods: We evaluated 103 patients with fixed implant-supported zirconia restorations (90 single crowns, 26 partial dentures, and 6 full arches) manufactured via computer-aided-design/computer-assisted-manufacturing and starting from the point of intraoral scans of novel CHAs (i-Physio®, LYRA-ETK, Sallanches, France). Patients were followed for one year.

Partial Extraction Therapy (Part 1): Applications in Full-Arch Dental Implant Therapy.

Partial extraction therapy (PET) is a set of surgical techniques that preserve a portion of the patient's own root structure to maintain blood supply derived from the periodontal ligament complex in order to maintain the periodontium and peri-implant tissues during restorative and implant therapy. PET includes the socket shield technique (SST), proximal shield technique (PrST), pontic shield technique (PtST), and root submergence technique (RST). In a traditional hybrid technique, total extraction and full-arch dental implant therapy often require significant bone reduction and palatal/lingual implant placement.

Partial Extraction Therapy (Part 2): Complication Management in Full-Arch Dental Implant Therapy.

Partial extraction therapy (PET) is a group of surgical techniques that preserve the periodontium and peri-implant tissues during restorative and implant therapy by conserving a portion of the patient's own root structure to maintain the blood supply, derived from the periodontal ligament complex. PET includes the socket shield technique (SST), proximal shield technique (PrST), pontic shield technique (PtST), and root submergence technique (RST). Although their clinical success and benefits have been demonstrated, several studies report possible complications.

The socket shield technique with proximal extensions for single-rooted teeth.

The conventional socket shield (SS) design extends from the mesiolabial to the distolabial line angle. C-shaped SS, L-shaped SS, and proximal SS designs have proximal extensions that help to maintain the hard and soft tissue in the interproximal areas. This is beneficial for implant sites adjacent to an existing implant or an edentulous space.

Guided Bone Regeneration of a Seibert Class III Bone Defect With Bioactive Calcium Phosphosilicate Bone Graft: Human Histology and Clinical Report.

This clinical case aimed to achieve two main objectives. The first was to determine if the use of only calcium phosphosilicate bone graft as a regeneration material (with no autologous bone added) on a severe vertical and horizontal mandibular defect would allow enough bone to be obtained to enable the placement of dental implants. The second objective was to determine histologic characteristics of the regenerated site after a healing period of 10 months.

The root submergence technique at single tooth sites to short-span edentulous sites: A step-by-step partial extraction therapy protocol.

Submerging roots for ridge preservation was the earliest partial extraction therapy and has been described since the 1970s. Despite the approximately 47 animal and human studies published since, an updated and contemporary step-by-step protocol has not yet been provided. This technique report describes in detail how to manage submerged roots at single tooth sites and at short-span edentulous areas.

Root submergence technique as a partial extraction therapy to preserve the alveolar ridge tissues: A systematic review and appraisal of the literature.

Statement Of Problem: As socket grafting with commercially available biomaterials has become popular, reports of the root submergence technique for ridge preservation have decreased. A systematic review of this partial extraction therapy is lacking.

Purpose: The purpose of this systematic review was to review the root submergence technique as well as critically appraise the available data.

Dimensions of the dentogingival tissue in the anterior maxilla. A CBCT descriptive cross-sectional study.

Background: The characteristics of the periodontium in anterior teeth influence the outcomes and prognosis of different periodontal, implant, and restorative procedures. In the present study, CBCT images were used to determine alveolar bone thickness and, to a lesser extent, gingival thickness. The aim was to evaluate the use of CBCT to measure the dentogingival complex in the anterior maxilla.

The Ball Technique for Peri-implant Soft Tissue Augmentation Using a Xenogeneic Collagen Matrix: A Technical Report.

In the maxillary anterior region, augmentation to correct a soft tissue deficiency is often required for an esthetic outcome and long-term implant therapy success. This case series of three patients presents a novel approach for soft tissue augmentation using xenogeneic collagen matrix balls in the esthetic zone around the implants. This technique avoids a secondary donor site compared to autogenous connective tissue graft.

Three-Dimensional (3D) Facially Driven Workflow for Anterior Ridge Defect Evaluation: A Treatment Concept.

The esthetic rehabilitation of anterior ridge defects and achieving patient satisfaction have become major clinical challenges for dentists and technicians. Poor diagnosis and treatment planning are frequently associated with multiple surgical procedures that fail to meet patient expectations. The loss of hard and soft tissues in anterior ridges results in an esthetically compromised zone that affects the rehabilitation prognosis.

Buccal Sliding Palatal Pedicle Flap Technique for Wound Closure After Ridge Augmentation.

One standard approach for wound closure after ridge augmentation is coronal flap advancement. Coronal flap advancement results in displacement of the mucogingival junction and reduction of the vestibulum. In the maxilla, a buccal sliding palatal flap can be applied for primary wound closure after ridge augmentation.

A decade of the socket-shield technique: a step-by-step partial extraction therapy protocol.

Ten years have passed since Hürzeler and coworkers first introduced the socket-shield technique. Much has developed and evolved with regard to partial extraction therapy, a collective concept of utilizing the patient's own tooth root to preserve the periodontium and peri-implant tissue. The specifications, steps, instrumentation, and procedures discussed in this article are the result of extensive experience in refining the socket-shield technique as we know it today.

A novel guided surgery system with a sleeveless open frame structure: a retrospective clinical study on 38 partially edentulous patients with 1 year of follow-up.

Background: This retrospective clinical study aims to present results of experience with a novel guided surgery system with a sleeveless, open-frame structure, in which the surgical handpiece (not the drills used for preparation) is guided.

Methods: This study was based on an evaluation of the records of partially edentulous patients who had been treated with a sleeveless open-frame guided surgery system (TWIN-Guide®, 2Ingis, Brussels, Belgium), between January 2015 and December 2017. Inclusion criteria were patients with good systemic/oral health and a minimum follow-up of 1 year.

The socket-shield technique at molar sites: A proof-of-principle technique report.

The socket-shield technique for avoiding postextraction tissue alteration was first described in 2010. The technique was developed for hopeless teeth in anterior esthetic sites but has not yet been described for molar sites. Managing postextractive ridge changes in the posterior region by prevention or regeneration remains a challenge.

Esthetic tunnel exposure: A combination technique for peri-implant soft tissue development at second-stage surgery.

An esthetically pleasing result is the product of both prosthetic excellence and the health and quality of the soft tissue that frames the restoration. Management of the peri-implant coronal soft tissue is key to the ultimate success of treatment. This technique report describes an alternative, novel approach, combining established concepts and methods into a single technique to improve esthetic results.

The "Scalloped Guide": A Proof-of-Concept Technique for a Digitally Streamlined, Pink-Free Full-Arch Implant Protocol.

Inadequate restorative space can result in mechanical, biologic, and esthetic complications with full-arch fixed implant-supported prosthetics. As such, clinicians often reduce bone to create clearance. The aim of this paper was to present a protocol using stacking computer-aided design/computer-assisted manufacturing (CAD/CAM) guides to minimize and accurately obtain the desired bone reduction, immediately place prosthetically guided implants, and load a provisional that replicates predetermined tissue contour.

This article presents the results of a soft tissue color study on flapless immediate implant therapy from a sample of 23 patients who received either a provisional restoration alone or with bone grafting. The gingival color in clinical photographs was measured for the implant and for the contralateral tooth site at 2.0 and 5.

Human Histologic Evidence of New Bone Formation and Osseointegration Between Root Dentin (Unplanned Socket-Shield) and Dental Implant: Case Report.

The socket-shield technique described 7 years ago has since grown in its reporting in the literature as a valid method of ridge preservation at immediate implant placement. To date, large clinical cohorts with up-to-4-year follow-up have been reported. Additionally, evidence of tissue histology at the dental implant and socket-shield has been demonstrated in the animal model.

A retrospective evaluation of 128 socket-shield cases in the esthetic zone and posterior sites: Partial extraction therapy with up to 4 years follow-up.

Objectives: Tooth loss results in an inevitable alveolar ridge reduction. This has established a cautionary approach to extract, wait, augment, and insert the implant, in lieu of immediate placement. However, saving the tooth or part of it whenever possible is more conservative and supports the vital periodontal tissue buccofacial to an implant.

Use of platelet-rich fibrin in regenerative dentistry: a systematic review.

Objectives: Research across many fields of medicine now points towards the clinical advantages of combining regenerative procedures with platelet-rich fibrin (PRF). This systematic review aimed to gather the extensive number of articles published to date on PRF in the dental field to better understand the clinical procedures where PRF may be utilized to enhance tissue/bone formation.

Materials And Methods: Manuscripts were searched systematically until May 2016 and separated into the following categories: intrabony and furcation defect regeneration, extraction socket management, sinus lifting procedures, gingival recession treatment, and guided bone regeneration (GBR) including horizontal/vertical bone augmentation procedures.

Partial Extraction Therapies (PET) Part 2: Procedures and Technical Aspects.

Part 1 of this series introduced the partial extraction therapies as a group of techniques for ridge preservation at immediate implant placement and beneath pontic sites. The concept proposes a paradigm shift away from extract and augment toward partly retaining the tooth root to preserve the ridge and prevent buccopalatal collapse. The revolutionary socket-shield technique was introduced in 2010; however, there has been no follow-up literature to guide the clinician in terms of procedural steps.

Partial Extraction Therapies (PET) Part 1: Maintaining Alveolar Ridge Contour at Pontic and Immediate Implant Sites.

Buccopalatal collapse of the postextraction ridge is a significant challenge in restorative and implant dentistry. A variety of ridge preservation techniques using tissue and augmentative materials have been proposed in the literature. A slightly different approach is to use the tooth itself.

The Palatal Bone Block Graft for Onlay Grafting Combined with Maxillary Implant Placement: A Case Series.

The aim of this study was to introduce an intraoral bone block harvesting technique--the palatal bone block graft (PBBG)--as an alternative harvest site for autogenous bone blocks. The PBBG technique was used to onlay graft esthetic zone defects simultaneous to implant placement in five patients. Measurable objectives were used to evaluate outcomes, and treatment was reassessed at up to 6 years.
